Abstract

The invention relates to the technical field of UV printing, in particular to low-temperature-resistant leather ink and a preparation method thereof. The low-temperature-resistant leather ink comprises the following raw materials in percentage by weight: 66-80% of acrylic ester, 4-6% of pyrrolidone, 4-10% of a photoinitiator, 8-20% of color paste, 0.1-1% of a flatting agent, 0.2-0.6% of a dispersing agent, 0.2-1% of a coupling agent and 0.05-0.3% of an antioxidant. The low-temperature-resistant leather ink provided by the invention has the following advantages: (1) the low-temperature-resistant leather ink has excellent low-temperature resistance and folding-resistant flexibility, and the folding-resistant times at -20 DEG C after the low-temperature-resistant leather ink is jet-printed on the surface of a leather soft material can reach 300,000 or more, which is far away from the level of products of the same type in supermarkets; (2) the appearance weather resistance is strong, and cracking and fading are not easy to occur; and (3) the raw materials are easily available, the process is convenient, and the application prospect is wide.

Description

Technical field [0001] The present invention relates to the field of UV printing techniques, and more particularly to low-temperature leather-resistant inks and preparation methods thereof. Background technique [0002] UV inkjet printing is a new type of printing technique, which is characterized by ultraviolet light, printing UV cured ink on the base; the technique can print the ink over the base of various materials, which can be molded once, No topped.
